I'm glad he/she was able to get something out of the deal. I don't recall seeing a situation in the past where a hedge was so unworkable, but I guess that's what happens when the odds of everything are so far out of bounds.
Here's a lesson I'll never need to learn - don't make your last pick of a 16 leg parlay a +400 moneyline pick!
If you want high odds you gotta play high odds.
